I am looking out a window that is 1.3m tall. A water balloon suddenly drops across the entire length of the window in .22 seconds. How far above the window was it dropped?
distance= vi*t+1/2 g t^2
1.3=vi (.22)+4.9 (.22^2) solve for vi, at the top of the windown.
now, distance to roof:
vabove^2=2 g h solve for h.
